Rak4631
Is this bug report about any UI component firmware like InkHUD or Meshtatic UI (MUI)?
Firmware Version
2.6.4.b89355f
Description
I am using the Plantower PMSA003I (RAK12039) connected to the RAK19007/3 baseboard with the RAK4631. I've noticed that the fan runs continuously, even when it's not measuring. The rotation speed increases during measurements, but it continues to rotate slowly during the intervals between measurements. This behavior consumes a significant amount of energy when running on batteries; for instance, it uses 40% of a 4000 mAh LiPo battery overnight.
RAKwireless technical support mentioned that the fan can be powered down. Ideally, I would suggest the following cycle: the fan should operate at a low rotation speed for two minutes, followed by PM concentration measurement, and then turn off completely.
